Appllcation filed July 8, 1918. Serial No. 243,899.

\ To all whom it may concern:

Be it known that I, FREDERICK R. BISHOP, a citizen of the ['nited States, residin at North Attlcboro, in the county of Bristol and State of Massachusetts, have invented certain new and useful Improren'ients in l lveglarssMountings; and I do declare the following to be a .full, clear, and exact description of the invention, such as will cnable others skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in eye glass mountings em iloying what is known as a shell rim and a metal lens holding ring circumscribed thereby. Hcretofore, considerable ditliculty has been en countered in preventing relative creeping of the ring and rim and for preventing slippage of the several metal clips upon the shell rim, said clips being employed for securing the bows, nose bridge, etc., to the lens carrying means. My invention aims to overcome these diliiculties in a simple and inexpensive manner, and with this object in view, the invention resides in the novel features of construction herein shown, described and claimed.

Figure 1 of the. accompanying drawing is an elevation of a pair of spectacles constructed in accprdancc with the invention.

Fig. 2 is a sectional perspective view of the construction employed in mounting the bows.

. Fig. 3 is a view similar to Fig. 2 but illustrating the manner in which the nose bridge is mounted.

Fig. 4 is a detail section on the plane indicated by the line of Fig. 3.

Fig. 5 is a sectional view throu h the shell rim and the lens holdin ring s owing more particularly the peri eral teeth on the latter which embed in t e former.

Fig. 6 is a sectional perspective view of a portion of the lens carrying ring.

In the drawing above briefly described,

the numeral 1 designates what is commonly.

termed a shell rim, this rim being constructed of tortoise shell, celluloid, or any other preferred material. The rim 1 is either split or continuous according to the style of the glasses and in all-cases said rim is provided with aninternal channel 2. A metal lens holding ring 3 is snugly re ceived in the channel 2 and is provided on its periphery with suitable teeth 4 which may be arranged in different ways to be forced into the bottom of the channel, thus serving to a large extent to prevent relative creeping of the rim and ring. The ring 3 is internally channeled at 5 to receive the edg'es of the lenses 6, and said ring may be either continuous or split as required. In the form of construction shown, both the rim 1 and the ring 3 are split, and on op 0- site sides of the split, the ring 3 is provi ed with laterally extending lugs 7 which project into the edges of the shell rim 1, thps effectively retaining the ring within the ri and further preventing possible shiftin o the two. A pair of U-shaped metal c ips 8 embrace the rim 1 adjacent the split, portion thereof and carry the usual ears 9 between which the bows 10 are pivoted at 11, said cars being clamped to ether in the usual manner by screws or the li e 12. The edges of the clips 8 are clenched around the edges of the shell rim 1 as seen at 13 and are clenched more deeply at o posite sides'of the lugs 7 than over them. iiy this means, the clenched edges 13 of the clips 8 are formed With shoulders 14 which abut the edges of the lugs, thus positively preventing slipping of the clips u on the ring'l. It will thus be seen that't e lugs in question nfivmly positively prevent any relative move natof the shell rim and the metal ringthere in, but that they will nit permit any sliding of the clips 8 upon m im. Furthermore, it. will be seen that the clenched edges of the clips eflectively retain the lugs embedded in the edges of the rim. The nose bridge 15 is provided with clips 8" similar to the clips the edges of said clips 8' being clenched a'round the edges of the shell rim 1 and lieing associated with lateral lugs 7 .on the ring 3, in the same manner as the lugs 7 and clenched edges 13 are related, and it will thus be seen that slipping of the clips 8 is prevented, a'ndat the same time the lugs 7 serve further to prevent relative shifting of the rim and rm rom the foregoing, taken in connection with the accom anying drawing, it will be obvious that alt ough my invention is of extremely simple and inexcnsive nature, it will be highly efiicient an in every way dosirable. Since probably the best results are obtained from the details shown and described, they are preferably followed, but

within the soope of the invention as claimed, considerable latitude is allowed for making such minor changes as occasion may dictate. For instance, the teeth 4 may be of an shape and arranged as required, but in a] instant-0s these teeth will be located on the periphvnr or largest diameter of the ring 3, since by this arrnn en'ient, the teeth may be embedded in the s \ell rim 1 by the simple p ocess of f reing one against the other.

I claim:

In an eye glass mounting, a shell rim having an internal channel, a metal lens holding rin in the channel of said shell rim, lateral llgt-f on the edges of said metal ring pro ecting mto the edges of said shell rim, and a metal clip embracing the portion of said shell rim into which said ln s roject, the edges of said clip being 0 enc ed around the edges of said shell rim and being clenched more deeply at o posite sides of said lugs than over" them, w lereby said in s prevent the clip from slipping on the she] rim and the letter from creeping on the lens holding ring.

2. A structure as specified in claim 1, together with peripheral teeth on said ring embedded in said shell rim.

In testimony whereof I have hereunto set, my hand.

FREDERICK R. BISHOP.
